Gas stations are situated near population centers, because you tend to run out of gas wherever you're driving, and you drive where you live.
In practice, consumer EVs almost universally charge at home[1] and "never" just "run out" of charge. You're car is always charged, there's little value to topping up at the shopping areas or whatever. Instead, you need DC fast charging where you travel: on the long distance arteries where your car can't otherwise reach.
To be clear: you need gas there too. But rural highway gas stations represent a small fraction of all gas service. Most gas stations won't be able to shift to EV charging and keep their business model.
[1] Though there are growing pains with apartment facilities being slow to install AC charging. Right now an EV works much better in a home with a garage, though that seems likely to sort itself out. Cheap electrical work is cheap, it's just a question of how to get people to pay for it. Some regulation is likely to be needed.
